I have two accounts, daniel and dn. When I log in with daniel first, everything is okay. But I can't login with dn, it freezes. It's irrelevant if I log out daniel or try a parallel login. It's the same way round with the account daniel if I log in dn first.

The desktop is shown, without any folders and I can't move the mouse.

Some information about the system:

64 bit dual boot Mint 16 MATE / windows 8

Both Systems on the same SSD / Secondary HDD

  • what df gives you ? last time I encountered something like this it was because of very low disk space on home partition – Kiwy Feb 18 '14 at 14:06
  • There is enough space on any partition, I added the output to the question. – Daniel Feb 18 '14 at 14:12
  • yes you're right, it worth a shot anyway. – Kiwy Feb 18 '14 at 15:27
  • If you create a third account with a different home dir (echo ~username), is the behavior the same? – user44370 Feb 18 '14 at 21:35
  • 1
    same behaviour. – Daniel Feb 18 '14 at 22:29

Looks a lot like an issue with your graphics card driver (nouveau) crashing when loading the second desktop for some reason (I am no kernel expert so I can't explain why).

I'd suggestion either:

  • Try a more recent kernel (you may need to build it yourself if there's none already available for Mint).

  • If you don't mind using proprietary software, try installing the latest driver from Nvidia.

I also notice mentions to Intel in your Xorg.log, are you by chance using one of those hybrid graphics laptops? If so, you can also try blacklisting the nouveau module entirely and see if you have any issues using only the Intel driver for the integrated graphics and see if it helps.

  • Thx, I switched to the nvidia driver, this problem is gone but now I have some other minor issues. Yes, it's one of these hybrid graphic cards. – Daniel Feb 25 '14 at 20:35
